Città, economia circolare e pianificazione urbanistica

Risultato della ricerca: Chapter


Globally, the progressive development of economic interdependence has caused the rapid growth of urban waste, leading the EU and UN to direct their attention onto urban policies and their effective integration. Cities and urban regions are the most critical areas where urban waste generation is concentrated, resulting in negative impact on human health and environment.For a long time, the urban waste increase has been considered as other pollutants a problem at the end of every production and consumption process and has been faced through sectorial tools, such as environmental directives and waste disposal plans at the regional level, neglecting the urban dimension. For some periods, Italian town planning has maintained this line by showing a certain reluctance to deal with an issue considered marginal and exclusive domain of sanitary engineering, disregarding its effects on urban landscape.However, an international process of awareness has generated a new systemic approach that tends to make explicit the sustainable development in urban environment and its link with the landscape. The attempt is disconnecting economic growth from environmental impact by promoting development models focussed on circular economy, which implies the reconversion of waste into resources. This can be developed through different kinds of economic-financial tools and especially through a management strategy of waste hierarchy within territorial optimal ambits by respecting proximity and self-sufficiency principles.In Italy, the territorial plans of coordination should strategically harmonize several typologies of environmental policies and urban plans with landscape protection. At this level of planning, the great waste-management infrastructures are localized through suitability analysis, with reference to their technology and size, scheduled by regions. However, waste managing plays a strategic role at all planning levels, from regional scale to urban design, in order to safeguard landscape and improve the inhabitants’ daily life. This means not only actively exploring integrated approaches in the waste sector, but also studying how to build an efficient web of small facilities and innovative services for waste collection in different morphologies of urban fabric. Definitely, both in historical centres and in outskirt neighbourhoods, each typology of buildings, streets, squares and open spaces that distinguish urban landscape implies a specific solution for renewing, stemming by a careful analysis.Therefore, this studio aims at highlighting some critical issues of town planning and its regulatory apparatus, which should include within urban standards advanced facilities for managing flows of waste in order to sustain circular economy and the quality of life in cities and urban regions. The chapter is based on the need of integration between urban plans and environmental policies, consequently implicating the use of innovative technological solutions applied to the urban fabric. Emergent from the applied research, some very synthetic suggestions are therefore outlined to implement smarter approaches for waste management in Sicily within small towns or neighbourhoods as opportunities for their ecological regeneration. The network of waste collection and small recycling plants plays effectively the role of a particular kind of ecological service, which makes valuable its spread for the urban metabolism.This system can contribute actually to build greener infrastructures that comprise a patchwork of ecological and technological proposals at different levels of
